Apple Music app crashes Iphone

So every time I try to play a song using the apple music app (my own music) the app crashes my entire phone. I just jail broke my phone to iOS 8.4. This crash also causes SpringBoard to crash. When I am in Safe Mode I can play music using the app just fine. I thought that something from the Jail Break might cause this but I didn't really install much myself. Only things I have personally installed are:
Classic Dock (I've disabled this again),Volume8, ToneEnabler, AppSynch Unified, CustomNotificationSound, DockShift (disabled that as well) and some theme which I have disabled as well.

Any idea what might cause this and how to solve this? I have only found people on the Net with the same problem but no solution.
